Field of the Invention The present invention relates to a suspended ceiling, and in particular to an improvement in a tau-shaped member for a metal grille constructed for such a ceiling. [Prior Art] Suspended ceilings typically include a rectangular grid formed by a parallel spaced main keel or tee and a secondary keel or tee extending vertically between the main keels. The secondary zi-shaped members typically have a plurality of end connectors that mate with identical coupling members of the other secondary jaws that are connected end to end. The joints of the secondary zi-shaped members are formed in the slots provided in the primary jaws. When a small grid module is used in a ceiling construction, the secondary jaws can also be slotted to receive the end connectors of the other secondary jaws. The thumb-shaped piece is typically made of a dry-formed metal plate (four), and the specifications of the plate (four) are different, so that the beak has sufficient strength for the task that it is desired to perform. The reason for this cost is not excessive. It is also common to use only the terminator configuration for all of its sub-zig configuration in terms of quotient, regardless of the degree of bowing used for the disc 4. Specification and Thickness of the Columns When the same secondary jaw type connector is used in a manufacturer's jaws, there may be a problem... a lighter gauge part is assembled by the -T-shaped connector. There will be sweaty and τ situations. This looseness adversely affects this tendency. The wearer's hand 201124594 may potentially affect the appearance of the grille along with the way the grille receives and other components of the ceiling. SUMMARY OF THE INVENTION = Improved assembly of slotted neutrals when a standardized secondary connector is received at a τ-shaped piece having different gauge thicknesses and/or spans for non-levels. The present invention relates to the production of 妩fm having a plurality of grid τ-shaped members of a range of operations. This reaction is carried out using different specifications of the slabs at the slots of their sub-pieces. Out-effective 2 In particular, the present invention contemplates that in the region of the τ-shaped θ-shaped member: the plurality of squat-shaped members receive the slot in the region of the slot, such that = the grid-shaped member is These regions have an effective thickness of a uniform sentence, which evolves over the entire range of the manufacturer's jaw load ratings. Τ In the embodiment with 2 excellent f, the 'one shed τ-shaped piece is permanently punched into a dent or recessed' of the τ-shaped slot slot and the connecting piece is broken to sit A leading edge region on the bottom of the indentation. Finished: The bottoms of the indentations of the τ-shaped members of different gauge thicknesses are formed at the same interval from the central plane. Because the connector is aligned therewith, the bottom surface of the indentation is used to determine the effective thickness of the slotted T-piece and, in accordance with the present invention, a glimpse of the 曰-shaped η-shaped piece has the same dimensions regardless of shape: What is the actual size of the material of the piece. Ideally, with reference to the dome/face view 'the indentation is laterally offset from the center of the slot, ^ the material displaced from the indentation of a connector does not substantially affect the shape in the dome 4 201124594 [Embodiment] of an opposite connector on the opposite side. A similarly offset dent is now referred to in the figures, here shown in the τ-shaped U, 12 (grouped for clarity in Figure 1, A small part of the hanging ceiling of the hanging ceiling at the point of intersection. _ , the slotted T-shaped piece or keel 丨丨 represents a main τ-shaped piece, which is typically 1 长度 in length. Or 12 feet (or metric equivalent) or - shorter secondary T-pieces - a main T-piece will have exactly the same slot 13' that is regularly spaced apart - and the secondary T-piece will have a relative There are fewer slots 13 or no slots at all. In the same view, the two opposite sub-zig members 12 intersect the slotted τ-shaped member u at the slot 13. The sub-zig members 12 The end connectors 14 are assembled, which are locked together in a known manner when both of them are properly inserted in the slot 13+. Lee 5,517,796 and 5,761, called herein incorporated by reference) discloses _ features like connection or terminal clamp 14. Although not shown 'but known in the industry, the secondary zi-shaped members 12 may have a plurality of slots and be intersected by other secondary zi-shaped members in the grille of the ceiling. The jaws 12, typically made of rolled sheet metal (usually steel 'which may be a hot dip galvanized product), and less often aluminum. The τ-shaped members 11, 12 are symmetrical about a central or intermediate vertical plane and generally include a lower convex, a rim 16, a vertical web 17, and an upper hollow reinforcing spherical member 18. Usually, when the - τ-shaped member is formed by sheet metal rolling, the web is a double-layered board. 201124594 According to a τ-shaped 侔1], the --Τ 件 二 2:: load or load level and if it is, - the thickness of the web η thick Tang is changed. The sum of the thicknesses can be a/n' if it is a double layer, which is the equivalent of the two layers, between 50 inches and 0.019 inches (or metric double value). When the end connectors 14 are inserted from the τ to the same slot by the * from the opposite side of the butt 11, the end of the material is connected (four) into the lock of the connector to the connector. The locking is actually by the edge 21 of the face 2 of the extension 24 of one of the locking systems - the opening 24 and the edge 23 of the / portion of the mating connector formed on each side - in a slotted shape The interlocking of the pieces η with the equal joint members 14 is precisely controlled in size, and the accuracy is increased. The change in size in the ceiling grille of #展不14 is expected to be such that the slotted jaws 11 are constrained by the pair of tees 12 by such connectors, such that 11 lateral movement and/or longitudinal distortion , ie, : τ-shaped piece - bar axis movement and / or twist quotient: contention: the longitudinal axis of the piece is manufactured with different strengths to two = contention, multiple 1 shape τ 涟 degree to meet the industry Or the national standard without the material content of the carpet excessively exceeds these standards. In order to meet this limitation, in addition to the material you used to construct this m & quotient using different specifications (thickness), the load grade M, the heavier the specification, the ceiling of the ceiling The greater the ability, the more the load level of the grid, the need to pay for the _ / τ system regardless of the end connector construction: the same 6 to be used for any of the sub-shaped members 12 201124594 conventional τ shape The thickness of the web Α ^ ^ ^ 双 匕 匕 and the need for a soap end or missing configuration - straight is a difficult problem. If the connection is two proportional to fit the thick web The slotted grille dome is loosely secured by the connectors. If a joint is proportioned to fit tightly with a conventional slotted jaw having a thin wall web, then it will It does not lock with the exact same connector of a person on a heavy wall, because such a thicker web will keep the material connector apart. The present invention locally changes the web of the slot. The problem of the slotted beak of the loose assembly is solved by the grille in the area Thus, regardless of the gauge thickness of their web material, they exhibit the same or nearly the same effective thickness for the connectors. Preferably, according to the invention, this is achieved by permanently moving the material adjacent to a slot. The adjacent area of the surface of one of the moving regions adjacent to such a connector that is adjacent to the groove of the grille having the other thickness has the same or nearly the same distance from the center of the web. The spacing. More specifically, the web material is permanently moved by a stamping operation to form a dimple 26. A surface 27 of the base of the dimple 26 has a predetermined distance D from the central plane 29 of the web 17 ( Figure 5) The dimple 26 is asymmetrical or offset to the left from a centerline passing through the slot 13. A leading edge 31 of a connector provided by a projection 32 on a laterally offset flange 33 is shown. Aligning with the indentation 26 and abutting the indentation bottom or base surface 27 to mark its position when the connector 14 is fully installed. The indentation 26 has sufficient area to receive the section of the protruding portion 3 2 such that the extension The exit portion defines the unique element of a pair of τ-shaped members for the relative position of the slotted 7 201124594 T-piece. As best shown in Figure 5, a dimple 26 is formed on each side or face of the web η 34. Ideally, the dimples 26 are offset from the centerline of the slot 13 by a sufficient distance so that they do not overlap. For production compared to the case where the indentations of the two sides 34 of the web 14 overlap each other The dimensional tolerances and forces of the tools of the indented surfaces 27 are not critical. The predetermined distance D of the indented surface 27 from the central plane 29 can be set to be the same as the outer surface of the thinnest web in a manufacturer's production line. The nominal size 'such that such lighter loaded jaws do not need to be stamped with a dent & is shown in Figure 3. Alternatively, a manufacturer may choose to set the private size to a nominal size corresponding to a medium load web and thus allow a lighter loaded web to have a slight between a pair of connected connectors But acceptable gaps. It is to be understood that the disclosure is by way of example only, and that various changes can be made by the addition, modification, or elimination of the details without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific details of the disclosure, except as the scope of the following claims. For example, the zi-shaped members can be configured to have indentations at the same location centered on the centerline of the slot on both sides of the web. Still further, for example, a beak having a lighter gauge (thinner web) can be plastically deformed in the region of the slot of the t-shaped member to have an effective thickness of a thicker web of a heavier load. And the connectors can be configured to engage with such regions. The present invention is applicable to a beak having a single layer web and is applicable to a tau piece having a flange structure of the type of .201124594 or a spherical configuration different from those shown.
